UBlueprintPathsLibrary::SetExtension
#include "Kismet/BlueprintPathsLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Sets the extension of the given filename, like ChangeExtension, but also applies the extension if the file doesn't already have one.
Caveats & Gotchas
- • Prefer this over ChangeExtension when you need to guarantee the result always has an extension, e.g. before constructing a save path.
- • Passing an empty InNewExtension strips any existing extension rather than leaving it untouched.
